To all whom it may concern:

Be it known that. I, lVILLIAMf BRYAN Morrow, a citizen of the UnitedStates, residing at Shippensburg, in the'county of Cumberland and Stateof Pennsylvania,

have invented new and useful Improvements in Screen-Door Fasteners, ofwhich the following is a specification.

This invention relates to improvements in door latches especiallyapplicable to light door frames such as screen doors and the like.

The invention contemplates the provision of a latch which whenoperatively associated with the door, the latter cannot be opened fromthe outside, and including a single element for interchangeableengagement with the latch lever at remote points whereby said latch maybe locked in operative or inoperative position as desired.

Among other features the invention embodies simplicity in 'constructon,and efficiency in operation, the invention residing in the construction,combination and arrangement of parts hereinafter more fully described.

In the drawing forming part of this application like numerals ofreference indicate similar parts in the several views and in whichFigure 1 is a transverse section through the door showing the latch inoperative position, the door jamb being in elevation. Fig. 2 is asimilar view showing the latch in inoperative position. Fig. 3 is asectional view taken on line aa of Fig. 1. Fig. 4 is a detail view ofthe latch lever.

In the specific embodiment of the invention illustrated, the sameconsists of a pair of spaced members 5 and 6 respectively,

fixed to the door jamb A, the inner edge of the member 6 being cut awayas at 7 for the reception of the semicircular bulged portion 8 of .thelever 9 to permit the rocking movement of the latter which is pivotedbetween the members 5 and 6 as shown. The lever at the opposite sides ofthe bulged portion 8 is adapted to engage the upper edge of the member 6to limit its movement in opposite directions. A plate 10 covers themembers 5 and 6 and is secured thereto in any suitable manner. Theforward end of the lever is adapted to enter an elongated recess 11 inthe door B, a keeper plate 12 extends transversely across the recess atthe lower end thereof and is terminally se- Specification of LettersPatent.

cured to the door in any suitable manner. The forward end of the leveris formed with a depending hook 13 adapted to hook over the'upper edgeof the plate 12 when posi- The under side of the hook is beveled as at14 so as to ride upon the upper edge of the plate 12, on closing of thedoor, and subsequently gravitate into operative association therewith.With the leverthus positioned within the recess 11, the dog 15 freelypivoted to the jamb A above said lever is swung forwardly intoengagement with the projection 16 extending upwardly from the'upper edgeof the lever and fitted within a transverse groove 17 in the end of thedog, whereby the lever is effectively held in operative position, andthe door securely locked in a manner to prevent of its being opened fromthe outside.

As clearly shown in Fig. 2 the dog15 is capable of being reversed, or inother words swung rearwardly into engagement with the projection 18rising from the opposite end of the lever to maintain the latter ininoperative position to permit the door to be opened and closed whendesired. The projection 18 has abeveled surface 19 for engagement with asimilar surface 20 on the lever 15, so that when the latter is swungrearwardly into engagement with the end of said lever, the latter willbe depressed thus lifting the forward end of the lever out of engagementwith the keeper plate 12 and locked in inoperative position, the beveledsurfaces 18 and 19 obviating any binding action between their respectiveparts during this operation. The member 5 serves as a stop for the pivotdog 15 limitingits movement in either direction, and-supports the samein operative engagement with the lever.

It is believed that from the foregoing descri tion the nature andadvantages of the invention will be readily apparent without requiring amore extended explanation and.

therefore the same has been omitted. It is to be understood however,that various changes may be resorted to when desired as fall within thescope of the appended claim.

What is claimed is A door latch and lock therefor compris ing incombination, a straight lever pivoted at a point between its ends to thejamb of the door for rocking movement, said lever being adapted to entera recess in said door arranged at a right angle to said lever, a keeperplate secured to the door and eX- tending across the lower end of therecess, said lever having a hooked end adapted to gravitate intoengagement with said plate upon entering said recess, projections risingfrom the upper surface of the lever at spaced points, a pawl freelypivoted above saidlever and having a notched end portion forinterchangeable engagement with said projection whereby to maintain saidlever in either operative or inoperative position, and means forlimiting the rocking movement of said lever.

In testimony whereof I affix my signature in presence of two witnesses.
